[Asterisk-Users] MS Messenger RTP

[Darren McIntosh]

I have noticed some strange behaviour when using messenger as a sip client.
Messenger appears to stop transmitting RTP like some sort of voice activity
detection, and some applications on asterisk also respond by ceasing/not
starting RTP transmission until they get something from messenger. Milliwatt
and ringback tone are examples of applications that stop sending. Voicemail
appears to keep transmitting regardless of what messenger is doing. Tried
using different codecs but the problem was consistent.

This is my first look at messenger as a sip client, so can anyone confirm
what I am seeing here is normal?  Using  CVS from 12/08/03 and messenger
4.7.2009. Both asterisk and messenger are in the same subnet.

cheers,
